The 4704 Series Interior and Exterior Extractor is a versatile and robust tool, designed to offer an efficient solution in the extraction of both internal and external components in machinery and engines.
This extractor comes equipped with two sets of interchangeable legs, allowing it to be adapted for different applications.
The 470405 model is designed for external extraction of parts with a diameter ranging between 40mm and 130mm, and for internal extraction with a range of 95mm to 150mm.
On the other hand, model 470415 is optimized for the internal extraction of parts with a diameter that varies between 45mm and 97mm.
Additionally, it can be configured in either a 2-leg or 3-leg mount, depending on the specific task need.
The system is complemented by two extraction options: the impact bar (available in 2kg and 5kg models) for applications where a dry and controlled blow is required, and a model 1110 bridge, which does not require additional adapters.
This tool is especially effective for disassembling cylinder liners, thanks to its self-centering system, which ensures a firm and balanced grip during the extraction process.

Recommendations for Use
Be sure to select the appropriate leg for the specific application (indoor or outdoor) to ensure a proper fit.
Check that the diameter of the part to be removed is within the working range of the chosen leg model (470405 or 470415).
Always use the impact bar or bridge as specified for the task to avoid damage to the tool or part.
Mount the extractor with 2 or 3 legs depending on stability and available space in the work area.
Apply even force when using the impact bar to avoid uneven wear or damage to the extractor legs.

Maintenance Recommendations
Clean the legs and other components of the extractor after each use to prevent the build-up of dirt and debris that may affect its performance.
Regularly lubricate moving parts to ensure smooth operation and extend the life of the extractor.
Periodically inspect legs and other critical components for signs of wear or damage, and replace any defective parts immediately to maintain tool safety and efficiency.
